  a. Glial cells within the lateral hypothalamus are key for the control of eating.
  b. The changes in eating noted in the first study are due to fibers that are passing through the lateral hypothalamus.
  c. The changes in eating are due to damage to cell bodies within the lateral hypothalamus, and these act to initiate eating.
  d. The lateral hypothalamus functions to inhibit eating.
  e. The investigator should have chosen a different inhibitory amino acid.

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
